--- Comment #6 from palmer at gcc dot gnu.org ---
Kito pointed out earlier today that it should already be possible to default to
libatomic via a --with-specs=... configure-time argument already, so one option
here would be to just add an example/reference spec to GCC. That would allow
distros to opt in to the "always link libatomic" behavior, if they want to risk
the ABI-related issues like we see in libstdcxx (which we'd of course have to
fix). It doesn't sort out the long-tail issues related to ABI compatibility
between GCC and LLVM (and the suggested mappings), but at least it gives folks
a unified mechanism for doing this.
I know it's pretty late, but that seems like something we could do on the
GCC-12 timeline. It seems like the distro folks are pretty fed up with waiting
so they're just going to backport/hack this if we miss GCC-12, might as well
have one way for that to happen.
